You don't need to post the specific code but you could post the "header" of the script with the "use" statements and the headers of the modules involved including a mock (empty) sub. In fact, I would recommend even for your own error-finding strategy to try and re-create the problem with as little code as possible - just some mostly empty modules with subs that just print "hello" or something. If you can re-create the problem, you have an easy set-up to debug and post it here.
